Ancient Predator Had a Killer Jaw | National Geographic

National Geographic



  • National Geographic on December 16, 2019

    The Helicoprion looked like a shark with a terrifying buzz saw in its jaw and had a bite as strong as a modern crocodile's. What are your thoughts on this ancient predator?

  • Rafael Leair on March 1, 2020

    They mentioned it briefly, but the idea that the shark looks like that is just a theory. There are many ways this sharks jaw could have looked.
    I also hate the horror theme. We dont need to be scared of sharks. Because of our fear, they are going extinct. Sharks are actually friendly and only eat when they're hungry. They wont mess with something like a human.

    I love this vintage horror movie feel!

  • Shaderox on March 18, 2020

    So… did i watch a short documentary or a poor horror movie pitch/trailer? cause i sure can't tell… im leaning towards the 2nd from the overall style

  • Lindsay Harrell on March 29, 2020

    Wow 😱😱😱😱

  • MEHNDI D QUEEN on April 9, 2020

    but i wounder what are the function of inner folded teeth

  • ahmet gurses on April 21, 2020

    great. now I got PTSD… from a long-extinct shark. Sweet dreams for me! xD

  • Sergio Alcantara on May 20, 2020

    Lmfaooo I thought the title said, “a kill*r Jew” 😂

  • Red on July 11, 2020

    Remember the Helicoprion isn’t a shark

  • Jaime Lion on July 26, 2020

    That’s one CARAZAY Fish
    Not crazy,
    Also, I actually really like this classic horror movie theme

  • Nart Darym on August 2, 2020

    How sure is the buzz saw shark existence? If it did exist could the bussaw is actually retractable tounge? Or sort of tentacle like?

  • Wicklash on August 7, 2020

    Now THAT could kill a megalodon. If it bit the tail off, or a fin. Imagine that. Sure its smaller by a little bit. But i think it could do it.

  • ꪑ᥅. ꫝꪮꪊᦓꫀ on August 13, 2020

    Giving me tha twilight zone and fallout vibes oh and bioshock lol.

  • youbob28 on September 23, 2020

    They found a coil of what they suspect are teeth. No proof whatsoever that this belonged to any species of shark. No way to even prove that this belonged in any fishes mouth but they've somehow discovered some new species of shark and know how big it was and how strong it's bite was. This is a fantasy world they are living in. Some pointy fossils tell nothing conclusive.

  • Zahra Fatima on October 25, 2020

    It so dangrous

  • Not RachelQ on November 26, 2020

    From hungry shark world buzz the helicoprion

  • DrawsWithoutAgoodReason on January 1, 2021

    i showed a picture of the shark to my parents AND IT TURNED INTO A LECTURE TO NOT BELIEVE IN EVERYTHING IM TOLD, they said that the shark is fake news!

  • Alaine Dave Rojo on January 27, 2021

    Hey let me ask How they eat ther Food

  • imthatguy on January 31, 2021

    Didn't sound too bad until he laughed

  • Death Song Gaming on February 18, 2021

    0:51 reminds me of when I used to pretend scissors were some animal’s mouth and made them eat paper

  • OcelotzNotFound on March 23, 2021

    Thanks for scaring me! Haha! (Don't worry the science is actually awesome!)

  • flyingSpaceCart on April 7, 2021

  • Alexander Ashrafi on April 25, 2021

    Helicorpion: I’m one of de most terrifying animal in the ocean!!!

    Megalodon: hold my beer

  • 55marpo on May 2, 2021


  • C Luke on May 10, 2021

    So how is it different than a port Jackson shark? I always wonder about these interpretation of fossils to make the creatures the most dangerous and scary when compared to modern animals with coevolution.

  • Arcanum on May 21, 2021

    Like that font

  • TheTriangle444 on May 24, 2021

    Thats crazy but inefficient. How can you store or hold your food or eat with that jaw and whats the purpose of all that teeth inside the circle. Thats probably how they died out and the normal jawed sharks survived

  • Sudha Parida on June 6, 2021

    why are you laughing.

  • Ethan’s science channel on June 12, 2021

    The Helicoprion is was not a shark 🦈 it was a chimera or as most people call it, a ghost shark or rat fish 🐟

  • Shouveek Banerjee on June 20, 2021

    Narrator : Hold my Laughter 😆

  • Gecks and gaming on July 2, 2021

    I wish I had a pet helicorion

  • Zenny on July 17, 2021

    how did it swallow its prey?

  • Chitose Greene on August 21, 2021

    Lol ik this is supposed to be serious but his face looks so ridiculous lol

  • obsidian on September 8, 2021

    if only the buzz saw could spin

    it could be a hundred times worse

  • zacky jack on September 13, 2021

    I thought it was as big as a nullshutk or something small AND ITS A 2GRET WATS

  • Vince the Worldly on October 7, 2021

    How do they know its not a shell of a mollusk?

  • Mohammad Nazlan on November 7, 2021

    Is this real?

  • Bandhan Mondal on December 17, 2021

    The more I watch this kind of creature in videos the more I think the game Prototype is pretty realistic
